Much easier to set up mining in datacentres near SWB (Solar + Wind + Batteries) with grid connection. When there is an oversupply from the grid or renewables (price may go negative), switch on the mining to absorb the extra electricity/stabilise the grid.
Tony Seba / Adam Dorr are suggesting cheapest SWB is 3-5 times the minimum power generation needed (in the future/at that time). 60-90+% of the time there will be an abundance of 'SuperPower'. ie - need 1GW peak/avg/minimum (unclear) - SWB will supply 3-5GW 60-90% of the time, only rarely dropping to sufficiency level for short periods (no wind, no sun, high demand).
